Using the timers can be intimidating if you start from t… Arduino Project Hub is a website for sharing tutorials and descriptions of projects made with Arduino boards Part 1 It is not usually long before new Arduino users discover that although the delay() function is easy to use it has side effects, the main one of which is that its stops all activity on the Arduino until the delay is finished (not quite true, I know, but that is usually how the problem presents itself). You start the delay and then when it is finished you do something. It needs to start when the program starts (as Millis() does) but then on an event, stop and on another event start again at zero. This is also a good test to check if your DFRobot LCD Keypad Shield works corr… Arduino Example 1: basic motion detect + LED Arduino Example 2: robust motion events (debounce + hold + cooldown) Arduino Example 3: alarm/relay trigger with arming + siren timer Common mistakes Troubleshooting (random triggers, no triggers, short range) Quick checklist 1) What PIR sensors detect (and why they false-trigger) Libraries The Arduino environment can be extended through the use of libraries.
